SAFETY RAZOR.

Application filed December 16, 1922. Serial No. 607,293.

T 0 all whom it may concern.

Be it known thatlt, LAURIER A. MAYNARD, a subject of the King of Great Britain, residing at Highland Park, in the county of \Vayne and State of Michigan, have invented certain new and useful Improvements in Safety Razors, of which the following is a specification, reference being had therein'to the accompanying drawings.

This invention relates to razors, and has special reference to the ordinary razor composed of a handle having a pivoted blade foldable relative to the handle.

One of the objects of my invention is to furnish the blade of an ordinary razor with a pivoted guard yieldably held at the cutting edge of the razor blade and adapted to be moved in advance of the cutting edge to smooth out or stretch the skin, to avoid wrinkles and loose flesh, thus facilitating shaving and adding" a degree of safety to the razor to' prevent the flesh from being cut or scratched.

Another object of this invention is to furnish a razor blade with a guard normally maintained in a plane parallel to the cutting edge of the blade, yet yieldable away from either side of the blade to permit of an intimate relation between the cutting edge and the skin either for right or left hand shaving.

A further object of this invention is to furnish an ordinary razor with an oscillatory or reciprocating mechanism by which a the razor blade may be rapidly vibrated to cause its cutting edge to sharply and expeditiously sever a hair. thus obviating the necessity of pulling the razor blade against hairs and cause the same to be severed.

A still furtherobject of this invention is' Fig. 2 is a cross sectional view taken on the line IIII of Fig. 1;

Fig. 3 is a similar view taken on the line IIIIII of Fig. 1;

Fig. 4 is a similar view taken on the line IV-IV of Fig. l; v

Fig. 5 is a view of 'the outer end of the razor blade provided with a guard;

Fig. 6 is a perspective view of a portion of the razor blade showing a modified form of mounting for one end of the guard;

Fig. '7 is a cross sectional view of the razor blade guard relative to a surface to be shaved, and

Fig. 8 is a perspective view of the complete razor.

In the drawing, the reference numeral 1 denotes a razor handle and pivotally mounted in an end of saidhandle is the shank 2 of a razor blade 3, said razor blade having a cutting edge 4:. 1

5 denotes a longitudinally disposed yieldable guard normally parallel to the cutting edge 4 of the blade 3 and normally in the same plane as said blade. but adapted to yield sidewise and permit of the cutting edge t engaging the skin with the guard 5 smoothing out or crowding the skin ahead of the cutting edge. as shown in Fig. 7 to facilitate shaving the skin. Usually a barber stretches the skin, particularly on the neck and fleshy portions of the face, with one hand while manipulating a razor with the other hand, and the guard 5 will automatically accomplish this result as the razor blade 3 is brought to bear on the skin and move over the surface thereof. The guard 5 is preferably in the form of a wire bail having its ends pivotally supported so that the bail may laterally shift relative to the cutting edge 4:. One end of the bail is disposed parallel to the end wall 6 of the blade 3 and this end of the bail terminates in a flat vertically disposed lug 7. while the opposite end of the bail terminates in a pintle 8.

9 denotes a resilient clamp-like mounting on the back edge of the blade 3. at the outer end thereof. and this mounting has an angularly disposed tongue or bearing 10 parallel to the end wall 6 of the blade 3 and provided with a triangular shaped opening 11 in which the bail lug 7 is loosely or pivotally mounted.

12 denotes a two-part casing-like mounting on the shank 2 adjacent the inner end of the blade 3, said mounting being in the form of plates having the upper edges thereof plates have barrels 15 held by the pintle 8 of the guard 5. This mounting has a set of angular stop arms or abutments 16 to limit the swinging movement of the guard 5, and another set of resilient arms 17 to normally hold the guard 5 in the plane of the blade 3. The arms 16 and 17 are operatively positioned relative to the inner end of the bail 5, and to prevent the mounting 12 from shifting longitudinally of the shank 2, said mounting has lugs 18 extending into grooves or recesses 19 provided therefor, in the walls of the shank 2.

2O denotes a mounting that may be used in lieu of the mounting 9 by providing the outer end of the blade 3 with a recess or seat 21 on or in which the mounting 20 may be secured to pivotally support the outer end of the bail 5.

22 denotes 'acasing clamped on the shank 2, between the handle 1 and the mounting 12, said casing having barrel edges 23 connected by a pintle or pin 24:- At the outer end of the casing are lugs 25 extending into grooves or recesses 26 of the shank 2 to prevent longitudinalmovement of the casing 22 independent of the shank 2.

27 denotes an outer casing or handle inclosing the shank casing 22. End walls of I the casing or handle 27 have openings 28' providing clearance for the ends of the shank casing 22 and the lower edges of the side walls of the casing or handle 27 have barrels 29 and pintles or rods 30 supporting a detachable bottom wall 31 of the casing or handle, such bottom wall permitting of the outer casing or handle being easily placed over the crank casing 22.

32 denotes a small compartment in the upper part of the casing 27, at the inner end thereof and this compartment is normally closed by a lid or cover .33 adapted to retain a suitable lubricant within 'the compartment. The inner end wall of the casing 27 has a bearing 34 for a shaft 35 extending into the. compartment 32, said shaft having its inner end provided with a cam wheel 36 and anti-frictional bearings interposed between said cam wheel and the bearing 34. The outer end of the shaft 35 is suitably coupled, as at 37 to a flexible shaft 38 in a tubing or casing 39 which is held by a coupling 40 mounted on the bearing 34:. The flexible shaft 38 and its tubular casing 39 are of a conventional form adapted to be connected to a suitable source of power, for nstance a small electric motor, and the tubmg or casing 39 may be held along the handle 1 by suitable lips or hold-fast devices 41 attached to said handle.

4C2 denotes transversely disposed pins or shafts carried by the casing or handle 27 and provided with rocker members or hell cranks 43 which have ends thereof pivot ally mounted between apertured lugs 44 of the shank casing 22. Opposite ends of the bell cranks 43 are pivotally connected, as at 45 to a reciprocatory rod 46. This rod has its inner end extending through an opening 4-7 in a wall of the compartment 32 with a resilient closure 48 normally closing the opening 47 to prevent waste of lubricant from the compartment 32. On the inner end of the rod 46 is a yoke or fork supporting a roller 49 which normally engages the cam face of the wheel 36 because of the retract-ile force of a spring 50 connecting the outer end of the rod 46 to the shank easing 22.

In operation, the rapidly driven cam wheel 36 causes the rod &6 to be reciprocated, rock the bell cranks 13 and oscillate or vibrate the shank casing 22 relative to the outer casing or handle 27. Since the razor shank 2 is firmly held by the casing 22the razor blade 3 will be rapidly shifted back and forth to cut hairs encountered by the cutting edge of the blade. This obviates the necessity of pulling the cutting edge 4 against hairs and permits of a surface being quickly shaved.

It is thought that the .operation and utility of my razor attachments will be apparent without further description, and. while in the drawing there are illustrated the preferred embodiments of my invention, it is to be understood that the structural elements are susceptible to such changes, in size, shape and manner of assembling, as fall within the scope of the appended claims.

What Iclaim is 1-- 1. The combination of a razor blade, a guard normally parallel to the cutting edge of the razor blade, means pivotally supporting the ends of said guard at the ends of the razor blade, means for limiting the pivotal movement of said guard, and means normally engaging said guard to produce pressure thereon when said guard is swung to one side or the other of said razor blade.

2, The combination called for in claim 1, wherein said means includes sets of arms, one set between the arms of the other set.

3. The combination of a razor blade, and guard adjacent said razor blade, to move in advance of said blade, and resilient means producing a'constant pressure on said guard when moved outward from the plane of said razor blade.

In testimony whereof I ailix my signature in presence of two witnesses.
